# KyBook vs Books Reader

The clearest difference is review sentiment: KyBook at 71% against Books Reader's 38%. KyBook also leads on update cadence (every 3 weeks vs every 3 months) and ratings volume (466 vs 22). Books Reader's advantage is rating (4.7 vs 4.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. KyBook sells 2 one-off in-app purchases and Books Reader sells 9 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Books Reader holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: KyBook has 466 ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 71% of KyBook's written reviews are positive against 38% of Books Reader's, so the app with the better star average is not the one people write more warmly about.

KyBook ships an update every 3 weeks, Books Reader every 3 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
